Perhaps we should close the LLVM bug as well?</p>

<p>Or do you think it still might be a bug, but rather fixed by unrelated changes in the code we generate?</p>

<p>I'd want to double-check the isolated code I put onto  <a href="https://bugs.llvm.org/show_bug.cgi?id=17261" target="_blank" title="https://bugs.llvm.org/show_bug.cgi?id=17261">https://bugs.llvm.org/show_bug.cgi?id=17261</a></p>

<p>I transcribed the <code>llc</code> invocations I used into that ticket, so I would hope it isn't that hard to double-check. (Assuming the <code>.ll</code> syntax in the files is still valid ...)</p>
